Kent state et al, were protests against a military machine that many of the protestors actually had to face in their lives via the draft.

Not like today. The current protestors with the cause dujour are daytrippers who do it for the endorphin hit of supposed moral outrage, even though they are often too young to really grasp the reality of these conflicts. For example, I was reading comments on you tube and someone joked about it being a 'second Mexican/American war'. Another person answered, "There was a first? When was that?". Those who don't know history are gonna doom us all...
